Texas Instruments CD74HCT688ME4 is an 8-bit identity comparator from the 74HCT series. This surface-mount device, packaged in a 20-SOIC, features an active low output that indicates when the two 8-bit inputs are equal (A=B). It operates over a supply voltage range of 4.5V to 5.5V with a quiescent current of 8 µA. The maximum propagation delay is 34 ns at 4.5V with a 50 pF load. This component finds application in digital logic systems, including industrial automation and consumer electronics, requiring precise comparison of binary data. The device is supplied in a tube.
